Abstract
A coil assembly includes at least one insulated wire and an electromagnetic interference shielding layer. The insulated wire is wound into a winding coil part. The winding coil part includes a first wire-outlet segment, a second wire-outlet segment and a central through-hole. The electromagnetic interference shielding layer is formed on the winding coil part for shielding the insulated wire. The electromagnetic interference shielding layer has lateral projection profile on the winding coil part. The electromagnetic interference shielding layer has a radial gap such that the electromagnetic interference shielding layer is a non-conducting loop.
